The study interprets the detective novel by Zygmunt Miloszewski, Ziarno prawdy (2011), while focusing in the fashion in which the novel analyses the mechanism of anti-Semitism. A significant role in the culprit ś plotting of a fake ritual murder is played by a city with a collective memory, which inspired the modus operandi of the act, when the murder made use of the rooted anti-Semitism of the local community. The myth of the ritual murder in the anti- Semitic interpretation originates through the distortion of the original meaning of the cultural units, their incorrect condensation and the rearrangement of their functions to incorrect positions. In the solution this projection of the culprit onto an „Other“ is discovered to be false, revealing that the worst crimes occur out of hatred behind locked doors. Miloszewski sets these current issues into the genre structure of a classical detective story with the solution abiding by the principles of fair play, while the thriller denouement through a found document is proved to be false.
